Sensitive - When someone challenges or criticizes INFJs’ principles or values, they are likely to receive an alarmingly strong response. People with the INFJ personality type are highly vulnerable to criticism and conflict, and questioning their motives is the quickest way to their bad side.
Extremely Private - INFJs tend to present themselves as the culmination of an idea. This is partly because they believe in this idea, but also because INFJs are extremely private when it comes to their personal lives, using this image to keep themselves from having to truly open up, even to close friends. Trusting a new friend can be even more challenging for INFJs.
Perfectionistic - INFJs are all but defined by their pursuit of ideals. While this is a wonderful quality in many ways, an ideal situation is not always possible – in politics, in business, in romance – and INFJs too often drop or ignore healthy and productive situations and relationships, always believing there might be a better option down the road.
Always Need to Have a Cause - INFJs get so caught up in the passion of their pursuits that any of the cumbersome administrative or maintenance work that comes between them and the ideal they see on the horizon is deeply unwelcome. INFJs like to know that they are taking concrete steps towards their goals, and if routine tasks feel like they are getting in the way, or worse yet, there is no goal at all, they will feel restless and disappointed.
Can Burn Out Easily - Their passion, poor patience for routine maintenance, tendency to present themselves as an ideal, and extreme privacy tend to leave INFJs with few options for letting off steam. People with this personality type are likely to exhaust themselves in short order if they don’t find a way to balance their ideals with the realities of day-to-day living.
